Optical fiber cassette and panel

Abstract

An optical fiber panel has a mount body having a front face with a plurality of cassette openings in adjacent arrangement. An optical fiber cassette including a cassette body and a fiber optic connector adapter is receivable through the cassette opening. The cassette body includes an adapter opening and a cable opening adjacent to the adapter opening, The fiber optic connector adapter is releasably attachable to the cassette body through the adapter opening. The cassette body includes a sidewall and a base wall extending from the adapter opening and the cable opening.

         5 . The optical fiber cassette of  claim 1 , wherein the cassette body comprises a retention member extending from the sidewall or the base wall, the retention member configured to receive a cable through an open end. 
     
     
         6 . The optical fiber cassette of  claim 5 , wherein the retention member is positioned within approximately 150 millimeters along the transverse direction from the cable opening. 
     
     
         7 . The optical fiber cassette of  claim 1 , wherein the cassette body comprises a pair of sidewalls separated from one another along the vertical direction. 
     
     
         8 . The optical fiber cassette of  claim 7 , wherein the pair of sidewalls is separated from one another along the vertical direction within one rack unit. 
     
     
         9 . An optical fiber panel, the panel defining a mutually orthogonal reference lateral direction, transverse direction, and vertical direction, the panel defining a reference front end and rear end separated from one another along the transverse direction, the panel comprising:
 a mount body comprising a front face, wherein the front face comprises a plurality of cassette openings in adjacent arrangement along the lateral direction; and   an optical fiber cassette comprising a cassette body and a fiber optic connector adapter, the cassette body comprising an adapter opening and a cable opening adjacent to the adapter opening, the fiber optic connector adapter releasably attachable to the cassette body through the adapter opening, wherein the cassette body comprises a sidewall and a base wall extending from the adapter opening and the cable opening.   
     
     
         10 . The optical fiber panel of  claim 9 , wherein the cassette body comprises a pair of sidewalls separated from one another along the vertical direction, and wherein the pair of sidewalls is separated from one another along the vertical direction within one rack unit. 
     
     
         11 . The optical fiber panel of  claim 10 , wherein the plurality of cassette openings comprises up to sixteen cassette openings within up to approximately five hundred millimeters along the lateral direction. 
     
     
         12 . The optical fiber panel of  claim 11 , wherein the adapter opening comprises up to eight fiber ports. 
     
     
         13 . The optical fiber panel of  claim 12 , wherein the panel is configured to receive a fiber density of up to 0.256 fibers per mm per rack unit. 
     
     
         14 . The optical fiber panel of  claim 9 , wherein the adapter opening and the cable opening are positioned in adjacent arrangement along the vertical direction. 
     
     
         15 . The optical fiber panel of  claim 14 , the cassette body comprising a retention wall at which the adapter opening is positioned. 
     
     
         16 . The optical fiber panel of  claim 9 , wherein the cassette body forms an interior volume. 
     
     
         17 . The optical fiber panel of  claim 16 , wherein the cassette body comprises an internal wall forming a routing pathway at the interior volume, wherein the routing pathway is positioned between the internal wall and the sidewall or end wall. 
     
     
         18 . The optical fiber panel of  claim 9 , wherein the cassette body comprises a retention member extending from the sidewall or the base wall, the retention member configured to receive a cable through an open end. 
     
     
         19 . The optical fiber panel of  claim 18 , wherein the retention member is positioned within approximately 150 millimeters along the transverse direction from the cable opening.
